I have have Ubuntu 7.10, and I just installed it, and am relatively new to linux (I've used it before, but I forgot everything).
Well, when I try to connect to my wireless network, I click on the monitor with the exclamation point at the top next to the clock, to see if I can see my wireless network. Well, I can't, nor can I see any other wireless network within its range. (I know there are some, my mac can connect to them fine.)
When I try to manually connect to it, it fails as if it doesn't see the network at all.
